At night, all the animals return to their homes to sleep. Birds dream in their nests, polar bears snore inside their ice caves, and children snuggle under the covers of their beds. Everything is in order. Unless, of course, it isn’t. Sometimes the world — or the book — gets turned upside down. And then things aren’t quite as simple.With its sweet, winsome illustrations, this book is perfect for sharing with children as they drift off into their own imaginative dreams.   Â
